First since this is a hybrid how much should I be dosing and how often?
If you look at the displacement rates of the powders you have listed and do a little research on homebrewing you will quickly discover how unlikely it is that the hybrid product you are describing is the one contained in that bottle. Does it list the carrier oil and/or the solvents?
List off any other compounds on the label and I can do a better job explaining as non-sciencey as I can why it isn't likely.
Also, the items that are blended don't make much sense together which again sets off my bullshit detector. The ratios are an issue too. Most legit blends keep deca lower than 1:1, C and E together is fishy as well given the context.
Even if it were legit there are practical reasons to not buy blends, like the inability to independently control your compounds which makes trouble shooting really difficult if problems arise.
If you are going to go ham, ala carte is the only way to eat.
